Manufacturing micro-LEDs on wafers has been a major challenge in terms of yield and cost. Most of the LED manufacturers today use sapphire wafers for manufacturing LEDs. These wafers are small in diameter and costly, which restrains the cost reduction of LED devices. ALLOS Semiconductors, Plessey Semiconductors, Aledia, and a few other players have developed GaN-on-silicon technology for manufacturing LEDs using conventional process. These companies are collaborating with the world's leading LED foundries to increase the manufacturing capacity on a large scale. https://www.marketsandmarkets.com/pdfdownloadNew.asp?id=119830236
